🔑 Key Concepts

Backend

An implementation of a database interface. Examples:

• Graph database backend for graph databases
• Vector database backend for vector databases
• In-Memory for testing

Factory

Mechanism for creating backend instances based on configuration.

• Looks up backend by name
• Instantiates the class
• Returns ready-to-use backend

Registry

System for registering backends so they can be discovered.

• Built-in backends auto-register
• Custom backends can be registered
• Supports querying available backends

Plugin Architecture

Design pattern that allows:

• Swapping implementations without code changes
• Adding new implementations easily
• Using configuration to select backends

---

🚀 Getting Started

1. Install Dependencies

pip install .

2. Set Configuration (.env)

GRAPH_DATABASE_BACKEND=neo4j
VECTOR_DATABASE_BACKEND=qdrant

NEO4J_URI=bolt://localhost:7687
QDRANT_URL=http://localhost:6333

3. Use in Your Code

from bamboo.database import GraphDatabaseClient

graph_db = GraphDatabaseClient()
await graph_db.connect()

4. Learn More

• Quick intro: DATABASE_PLUGINS_QUICK_REFERENCE.md
• Full docs: DATABASE_PLUGINS.md
• Examples: DATABASE_PLUGINS_EXAMPLES.md
